Todos n\u00f3s usamos dispositivos el\u00e9tricos<\/a> Diariamente, ouvimos termos como "\u00e0 prova d'\u00e1gua", "resistente \u00e0 \u00e1gua" e "\u00e0 prova de poeira". J\u00e1 se perguntou como isso funciona ou como esses termos s\u00e3o chamados no mundo industrial? Se n\u00e3o, este artigo explica tudo. Eles s\u00e3o conhecidos como classifica\u00e7\u00f5es IP, que ajudam a determinar o n\u00edvel de prote\u00e7\u00e3o de um dispositivo.<\/p>\n

Entendendo o prop\u00f3sito e o significado da classifica\u00e7\u00e3o IP<\/h2>\n

Quantas vezes seus aparelhos el\u00e9tricos e eletr\u00f4nicos quebraram por causa de \u00e1gua, ou o ventilador da sua m\u00e1quina ou motor\/gerador emperrou por causa de poeira? Para entender as medidas de seguran\u00e7a necess\u00e1rias para proteger seus investimentos, Comiss\u00e3o Eletrot\u00e9cnica Internacional (IEC) <\/a>\u00a0Foram criadas as classifica\u00e7\u00f5es de prote\u00e7\u00e3o contra ingresso (IP).<\/p>\n

Essa classifica\u00e7\u00e3o \u00e9 uma informa\u00e7\u00e3o codificada sobre equipamentos e dispositivos. Ela indica o qu\u00e3o bem a carca\u00e7a de um dispositivo impede a entrada de poeira e l\u00edquidos. Essas classifica\u00e7\u00f5es s\u00e3o muito utilizadas em diversos setores. Muitos t\u00e9cnicos e prestadores de servi\u00e7os querem entender termos complexos como "\u00e0 prova d'\u00e1gua" ou "resistente \u00e0 \u00e1gua" quando usados para fins de marketing.<\/p>\n

A classifica\u00e7\u00e3o IP \u00e9 impressa com 2 algarismos, mas \u00e0s vezes um n\u00famero ou letra adicional (n\u00e3o obrigat\u00f3rio) tamb\u00e9m \u00e9 impresso.\"47w\"<\/p>\n

Primeiro n\u00famero<\/h3>\n

Na imagem acima, voc\u00ea pode ver a sigla IP com os n\u00fameros 4, 7 e W. O primeiro d\u00edgito do c\u00f3digo representa o n\u00edvel de resist\u00eancia do dispositivo a part\u00edculas s\u00f3lidas. A escala varia de 0 a 6. Voc\u00ea aprender\u00e1 mais sobre isso nas se\u00e7\u00f5es seguintes.<\/p>\n

Segundo n\u00famero<\/h3>\n

Da mesma forma, h\u00e1 outro n\u00famero junto com o primeiro d\u00edgito. Este 2e<\/sup> O n\u00famero indica a resist\u00eancia do inv\u00f3lucro ao contato do material l\u00edquido com o dispositivo. Da mesma forma que o primeiro d\u00edgito, ele tamb\u00e9m possui uma escala que varia de 0 a 9.<\/p>\n

D\u00edgito ou letra adicional<\/h3>\n

Junto com os dois d\u00edgitos, \u00e0s vezes voc\u00ea ver\u00e1 um terceiro d\u00edgito ou uma letra tamb\u00e9m. Isso \u00e9 fornecido pelo fabricante caso haja alguma informa\u00e7\u00e3o adicional importante sobre o produto. o recinto<\/a> \u00c9 necess\u00e1rio informar o usu\u00e1rio. \u00c9 opcional e n\u00e3o \u00e9 comum, exceto em dispositivos de uso espec\u00edfico que operam em ambientes especiais.<\/p>\n

Entendendo os C\u00f3digos de Classifica\u00e7\u00e3o IP<\/h2>\n

A classifica\u00e7\u00e3o IP \u00e9 crucial na sele\u00e7\u00e3o do equipamento certo em setores como constru\u00e7\u00e3o, manufatura, embalagens e alimentos e bebidas. Um exemplo disso \u00e9 o painel de controle de um guindaste de constru\u00e7\u00e3o, que pode ter classifica\u00e7\u00e3o IP56. Isso significa que ele \u00e9 protegido contra poeira e tamb\u00e9m contra jatos de \u00e1gua potentes.<\/p>\n

A classifica\u00e7\u00e3o IP69K oferece a mais alta prote\u00e7\u00e3o, tornando o inv\u00f3lucro \u00e0 prova de poeira e seguro contra jatos de \u00e1gua potentes e de alta temperatura.<\/p>\n

Em quase todos os sistemas hidr\u00e1ulicos e m\u00e1quinas pesadas, os componentes el\u00e9tricos e pneum\u00e1ticos s\u00e3o protegidos por inv\u00f3lucros com classifica\u00e7\u00e3o IP. Por exemplo, as caixas de circuitos s\u00e3o constru\u00eddas com componentes eletr\u00f4nicos sens\u00edveis e os pain\u00e9is de controle s\u00e3o de diversos tipos. Hydraflu<\/a> Equipamentos hidr\u00e1ulicos e outras m\u00e1quinas cont\u00eam diversos componentes e placas de circuito.<\/p>\n

Todos os equipamentos similares que contenham componentes eletr\u00f4nicos precisam ser protegidos, caso contr\u00e1rio, as chances de mau funcionamento ou de causar ferimentos aumentam \u2013 principalmente se expostos a poeira ou l\u00edquidos. H\u00e1 varia\u00e7\u00e3o na classifica\u00e7\u00e3o dos equipamentos dentro do mesmo andar de trabalho. Essa varia\u00e7\u00e3o existe porque diferentes componentes de um sistema maior s\u00e3o instalados em posi\u00e7\u00f5es diferentes, de modo que cada posi\u00e7\u00e3o definir\u00e1 qual ser\u00e1 o n\u00edvel de prote\u00e7\u00e3o. Classifica\u00e7\u00e3o IP<\/a> Qual \u00e9 o melhor lugar para se estar? Isso ser\u00e1 abordado nas pr\u00f3ximas se\u00e7\u00f5es.<\/p>\n

Agora, vamos apresentar os gr\u00e1ficos de refer\u00eancia abaixo para uma melhor e mais r\u00e1pida compreens\u00e3o da classifica\u00e7\u00e3o IP.<\/p>\n

Classifica\u00e7\u00e3o de part\u00edculas de poeira<\/h3>\n

\"N\u00edveis<\/p>\n

O primeiro numeral no c\u00f3digo de classifica\u00e7\u00e3o IP acima, ou seja, "4", representa o n\u00edvel de prote\u00e7\u00e3o do dispositivo ou da carca\u00e7a contra part\u00edculas de poeira. Conforme a tabela abaixo, 4 significa que ele est\u00e1 protegido contra part\u00edculas com tamanho de 1 mm. A tabela abaixo descreve os n\u00edveis de prote\u00e7\u00e3o para part\u00edculas s\u00f3lidas. Voc\u00ea pode aprender mais sobre isso criando um c\u00f3digo de exemplo.<\/p>\n

N\u00edveis de prote\u00e7\u00e3o contra entrada de l\u00edquidos<\/h3>\n

\"Prote\u00e7\u00e3o<\/p>\n

L\u00edquidos s\u00e3o inimigos da eletr\u00f4nica, sejam eles \u00e1gua ou \u00f3leo. Por isso, o n\u00famero IP \u00e9 um dos mais importantes. Quanto maior o n\u00famero, melhor a prote\u00e7\u00e3o contra a entrada de l\u00edquidos. A tabela abaixo, "N\u00edvel de Prote\u00e7\u00e3o contra L\u00edquidos Hydraflu", apresenta o c\u00f3digo e a descri\u00e7\u00e3o de cada componente.<\/p>\n

3rd<\/sup> D\u00edgito ou letra (opcional)<\/h3>\n

O terceiro d\u00edgito geralmente n\u00e3o consta na classifica\u00e7\u00e3o, a menos que haja uma necessidade cr\u00edtica de mencion\u00e1-lo. Voc\u00ea tamb\u00e9m pode aprender isso, pois, por precau\u00e7\u00e3o, pode ser necess\u00e1rio manusear equipamentos com um d\u00edgito adicional.rd<\/sup> A letra que vem antes ou depois dos dois d\u00edgitos principais. Esse conhecimento evitar\u00e1 que voc\u00ea se confunda caso essa situa\u00e7\u00e3o ocorra.<\/p>\n

O terceiro d\u00edgito\/letra indica algumas instru\u00e7\u00f5es ou informa\u00e7\u00f5es especiais que voc\u00ea pode precisar ter em mente juntamente com os outros 2 d\u00edgitos.\"Letras<\/p>\n

Agora, se voc\u00ea voltar \u00e0 primeira imagem, onde um c\u00f3digo IP de exemplo \u00e9 fornecido como IP47W<\/u><\/em><\/strong>, Voc\u00ea pode interpretar o significado deste c\u00f3digo seguindo as instru\u00e7\u00f5es de todos esses gr\u00e1ficos. Experimente como exerc\u00edcio de compreens\u00e3o e voc\u00ea poder\u00e1 aplicar essa t\u00e9cnica em todas as situa\u00e7\u00f5es reais futuras.<\/p>\n

Fatores que podem degradar a prote\u00e7\u00e3o da propriedade intelectual<\/h2>\n

A classifica\u00e7\u00e3o IP \u00e9 um valor determinado pelos testes realizados durante a fabrica\u00e7\u00e3o do equipamento ou dispositivo. O produto passa por um teste de garantia de qualidade, e a classifica\u00e7\u00e3o IP \u00e9 definida de acordo com esse teste. No entanto, com o uso e a opera\u00e7\u00e3o do equipamento, a classifica\u00e7\u00e3o IP se degrada com o tempo. Isso pode ocorrer por diversos motivos, como:<\/p>\n

    \n
  1. O dispositivo foi danificado e, assim, part\u00edculas de poeira ou l\u00edquido encontraram um espa\u00e7o ou rachadura para entrar na carca\u00e7a ou no inv\u00f3lucro.<\/li>\n
  2. Riscos ambientais como derramamentos de produtos qu\u00edmicos, atmosferas polu\u00eddas quimicamente, temperaturas extremas ou umidade desempenham pap\u00e9is significativos na degrada\u00e7\u00e3o das classifica\u00e7\u00f5es IP.<\/li>\n
  3. Da mesma forma, o desgaste prolongado tamb\u00e9m degrada as classifica\u00e7\u00f5es IP.<\/li>\n
  4. Um dos fatores cr\u00edticos \u00e9 instalar equipamentos com um entendimento incorreto da classifica\u00e7\u00e3o IP desses equipamentos. Eles n\u00e3o se encaixar\u00e3o no local correto e, portanto, degradar\u00e3o rapidamente a classifica\u00e7\u00e3o IP.<\/li>\n<\/ol>\n

    Por isso, compreender a classifica\u00e7\u00e3o IP em rela\u00e7\u00e3o \u00e0 utiliza\u00e7\u00e3o e aplica\u00e7\u00e3o de instrumentos e equipamentos \u00e9 fundamental. Portanto, acesse a pr\u00f3xima se\u00e7\u00e3o para obter mais detalhes sobre esse conceito.<\/p>\n

    Como entender a classifica\u00e7\u00e3o IP mais adequada<\/h2>\n

    A escolha da classifica\u00e7\u00e3o IP correta depende do ambiente em que seu dispositivo ser\u00e1 utilizado, equilibrando custo e os n\u00edveis de prote\u00e7\u00e3o necess\u00e1rios. Muitos fatores cr\u00edticos contribuem para a sele\u00e7\u00e3o do equipamento com a classifica\u00e7\u00e3o IP mais adequada. A seguir, apresentamos a tabela com a classifica\u00e7\u00e3o IP mais apropriada em rela\u00e7\u00e3o ao ambiente e \u00e0s situa\u00e7\u00f5es:\"Exemplos<\/p>\n

    Classifica\u00e7\u00f5es IP mais comuns<\/h2>\n

    A classifica\u00e7\u00e3o IP espec\u00edfica s\u00f3 pode ser determinada corretamente se voc\u00ea e o fabricante avaliarem cuidadosamente o ambiente operacional. Para fins de compreens\u00e3o, considere as classifica\u00e7\u00f5es IP56 ou IP66, que s\u00e3o as mais comuns e adequadas para a maioria das condi\u00e7\u00f5es ambientais. Da mesma forma, verifique as especifica\u00e7\u00f5es dos diferentes dispositivos e sua localiza\u00e7\u00e3o no local de trabalho.<\/p>\n

    Conclus\u00e3o<\/h2>\n

    Compreender as classifica\u00e7\u00f5es IP ajuda voc\u00ea a selecionar dispositivos dur\u00e1veis que atendam \u00e0s suas necessidades de prote\u00e7\u00e3o, aumentando sua vida \u00fatil e desempenho. O ponto crucial \u00e9 entender as condi\u00e7\u00f5es ambientais em que o equipamento ou o painel de controle da m\u00e1quina ser\u00e1 instalado. Se esse c\u00e1lculo for feito com cuidado, o equipamento ter\u00e1 uma vida \u00fatil mais longa.<\/p>\n
